Q: All of the following are likely to cause Sterile pyuria except?

A) Gonorrhea
B) Acetaminophen intake
C) Genitourinary tuberculosis
D) Urosepsis
E) Kawasaki disease


Answer:  D 

Sterile pyuria is defined as a urine specimen which contains white blood cells but stays sterile by any standard culturing techniques. Any WBC count without positive culture in urine should be glanced again to rule out any other underlying disease. Urosepsis, on the other hand, is term broadly used to describe generalized sepsis and bacteremia due to positive bacteriuria. 

The objective of above question is to recall diseases which may cause sterile pyuria and may lie low for diagnosis.
